Return clinical trial data to the patients who made it possible.

EBB gives clinical trial participants meaningful, plain-language access to their own study data, generating personalised plain-language trial summaries, delivered securely at study close. Regulators are beginning to expect this from sponsors. Patient advocacy groups are demanding it. Evidence shows that data return improves retention, recruitment for future studies, and builds long-term trust in clinical research.

EBB makes doing the right thing easy.

Why it matters

Participants give everything. Most get nothing back.

Clinical trial participants contribute months or years of their lives, their health data, and their trust to research that benefits millions. Yet when a study ends, most receive no meaningful information about their own results.

Regulatory pressure is increasing. ICH E6(R3) and evolving FDA guidance are pushing sponsors toward participant data return as a standard of care. Patient advocacy groups are demanding it. Evidence shows that data return improves retention, recruitment for future studies, and builds long-term trust in clinical research.

98%
of clinical trial participants in a breast cancer study wanted to receive their trial results. (TACT trial, n=1,431; Jenkins et al., BMC Cancer, 2008)
75%
of patients surveyed at the Royal Marsden felt that participants should be informed of trial results. (n=249; Atiqa et al., 2016)
90%+
of participants in global surveys report wanting to understand their data and know that their participation made a difference. (Pfizer Clinical Trial Alumni Programme, 2024)
51%
of prospective trial participants are motivated by success stories from prior participants, underscoring the recruitment value of visible data return. (Clinical Trial Participation Statistics, 2026)
TransCelerate BioPharma's Individual Participant Data Return (iPDR) initiative, completed in August 2025, produced a four-part resource package to help sponsors operationalise data return: a socialization presentation, a considerations guide, a customisable implementation template, and a webinar series. The initiative acknowledges that while participant demand is clear, the frequency, timing, and type of data returned today is varied and not widespread.

The MRCT Center at Brigham and Women's Hospital and Harvard has identified data return as consistently desired and often expected by research participants, publishing guidance and case studies since 2017 to support sponsors in implementing compliant return pathways.

No feedback loop

Participants rarely learn what happened in the study they helped run. Exit interviews show this is one of the most common sources of disappointment.

2

Growing regulatory expectations

ICH E6(R3), the FDA's patient-focused drug development guidance, and GDPR Article 20 all point in the same direction: participants have a right to their data.

3

Retention and recruitment at risk

Studies that return data to participants report higher completion rates and significantly greater willingness to join future trials. Data return is not just ethical: it is strategic.

How it works

From study data to participant report in three steps.

STEP 01

Upload or stream your data

Sponsors or CROs upload SDTM-structured data to the EBB platform.

STEP 02

EBB generates a personalised report

For each participant, EBB produces a plain-language, branded PDF report. Clinical values are shown alongside reference ranges and plain-English explanations. Charts, tables, and quality of life scores are included where data permits. No two reports are identical.

STEP 03

Deliver to site or directly to participants

Reports are distributed to the investigative site for onward sharing, or sent directly to participants via secure email with a single click. Delivery is logged in a tamper-evident, 21 CFR Part 11 compliant audit trail.

Participant data is never stored at the application layer: it passes through, is used to generate the report, and is not retained. This means a simpler compliance footprint for sponsors and stronger privacy guarantees for participants.
For sponsors and CROs

Meet your data return obligations without adding operational burden to busy teams.

As regulatory expectations evolve, returning data to participants is moving from best practice to standard requirement. EBB gives your team a structured, auditable, and repeatable process, without building custom tooling or diverting valuable resource.

Whatever type of study you are running across multiple countries and sites, EBB scales to your participant count and adapts to your study design and local requirements.

TransCelerate's iPDR Considerations Guide advises sponsors on how to build a business case for data return, identify operational impacts, and determine what data to return and to whom. EBB is built to align directly with this framework, accepting standard SDTM domains and generating reports that meet the TransCelerate template's content recommendations.

ICH E6(R3), effective from May 2025, reinforces the principle of participant-centred research and places greater emphasis on transparency, quality by design, and the rights of participants. EBB's audit log is designed to meet 21 CFR Part 11 and ICH E6(R3) requirements as standard.
ICH E6(R3) Good Clinical Practice Guideline, 2025.
  • Accepts standard SDTM domains: no reformatting required
  • Generates personalised, branded PDF reports including Plain Language Study Summary at scale
  • Delivery to site or direct to participant via email. Sponsor controls when sent to protect blinding and data integrity
  • Full GxP audit trail: 21 CFR Part 11 and ICH E6(R3) compliant
  • Supports multiple concurrent studies from a single portal
  • Role-based access for sponsors, CROs, and site staff
  • Configurable report branding per study
For patients and advocates

Clinical trial participants deserve to know what their contribution found.

EBB was built with participants in mind. Every report is written in plain language, not clinical notation. Values are explained and put into context for individuals, charts are labelled, and the language assumes no medical background or advanced health literacy.

For patient advocacy organisations, EBB offers a concrete way to push for participant data return as a standard across the trials your community participates in. We work with advocacy groups to understand what participants most want to see in their reports, and we build that in.

96%
of healthcare professionals agreed that trial results should be written in lay terms for patients. (TACT trial; Jenkins et al., BMC Cancer, 2008)
44%
of participants wanted results communicated directly from the trials office rather than via their hospital, indicating appetite for direct digital delivery. (TACT trial, n=1,431)
The MRCT Center's return of individual results framework, which informed both Pfizer's Clinical Trial Alumni Programme and TransCelerate's iPDR Package, identifies plain-language communication and contextual explanation as essential elements of any compliant data return. EBB reports are designed to these standards.

Plain language, always

Clinical values like SYSBP and LBORRES are translated into 'Your systolic blood pressure' and 'Your result'. Reference ranges, plain-English flags, and contextual notes are included throughout.

Built around the participant

Reports include a personal summary, visit-by-visit charts, quality of life scores compared to age-matched population norms, a side effects summary, and a clear next steps section.
